Abstract: A method and structure for for displaying an optimal tactile display, comprising transforming a CAD image into physical dimensions and creating an optimal tactile display reflective of the physical dimensions utilizing instructions from one or more microcontrollers. The optimal tactile display comprises an array display surface comprising a collection of controlled pins, a quantity of controlled pins propositional to a size of the physical dimensions, wherein each pin assembly of the controlled pins configured to be extended pins based upon the size of the physical dimensions, a plurality of planetary motors, each of the planetary motors associated with the controlled pins and configured to move the plurality of pins, a control unit to monitor the extension of the plurality of pins, and respective linear actuators configured to drive a respective motor shaft connected to a respective lead screw, each respective lead screw placed inside of each of respective threaded circular cross-section stoke tube.
